![(7) In wild animals which are confined, I have several times observed elonga- tion and deformity of the claws—in dogs it is sometimes the cause of lameness. v. Blaine On the Diseases of Dogs.—In oxen I have seen it several times; a short time since I possessed two ox feet, in which the hooflets were four inches long, and completely cylindrical;—in the horse there is very frequently mal- formation of the hoof, as flat-hoof, bound-hoof, brittle-hoof, pomet-foot, ass-hoof, &c.; in domestic birds the monstrous elongation of the claws is very common. (8) Compare especially Roger Collard. (9) The monsters, No. 2906 and 2917, of the Bres]. Mus. exhibit such nails, the latter a common nail for the fingers of the right hand; cases of this kind were also noticed by v. Walther Ueber die angebornen Fetthautgeschwiil-ste und andre Bildungsfehler, p. 31. fol. Landshut, 1814. I saw a consolidation of the four outer nails of both hands of a remarkable thief in the Anatomical Museum at Freyburg. Something similar occurs in the undivided hoofs of pigs, v. Ozto Selt. Beob. Part II. p. 83. I have since procured the skeleton of a pig of this kind for the Museum, No. 4652, and saw in the Veterinary School at Stockholm, three full-grown swine with the same deformity.

The cotour of the nails is not unfrequently irregular, thus in many diseases they lose their gloss, reddish colour, and natural transparency; or WHITE STREAKS, seline, are produced in consequence of partial or deficient nourishment; they even become entirely wHITE, which has been once observed in a paralytic person ;’ sometimes the normal white streak, dunula, is deficient ; in jaundice they assume a YELLOw colour; some- times yellow and red streaks are produced, as in the hoof of a horse affected with the so-called corns; they appear pusky and BLUISH in the blue disease, in suffocation, after bruises, in which blood is collected beneath them; they have been seen BLACKISH in some diseases.” The nails are also easily coloured either accidentally or purposely in various ways, for instance, yellow, brown, and even black, in baths containing iron and sulphur,’ reddish in baths of red madder; in dyers, tanners, hat-makers, they are often deeply coloured, and many nations have the custom of colouring their nails.* (1) Loder Medic. chir.

We frequently find the consisTENCE and TEXTURE of the nails morbidly changed, either alone or generally together with similar changes in the cuticle.
